LNBTVS4-304S

STMicroelectronics · TVS · SMC

LNBTVS4-304S from STMicroelectronics, in a SMC. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode of the unidirectional Transil, marked by the cathode band on the package; connect to the protected LNB supply/output line (VRM 28 V, VBR 31.5 V min at 1 mA).
2 A passive Anode of the unidirectional Transil, connected to ground; clamps at VCL max 45 V (8/20 µs, 334 A) and 56 A (10/1000 µs).
